What is MEMS?


Micro-Electro-Mechanical Systems (MEMS) is the integration of a number of microcomponents on a single chip which allows the microsystem to both sense and control the environment. The components typically include microelectronic integrated circuits (the “brains”), sensors (the “senses” and “nervous system”), and actuators (the “hands” and “arms”).


The components are typically integrated on a single chip using microfabrication technologies. The electronics, mechanical and electromechanical components are fabricated using technologies borrowed heavily, but not exclusively, from integrated circuit fabrication technology. There are three principal steps:

  1. Deposition processes - thin films of material are placed on a substrate
  2. Lithography - a patterned mask is applied on top of the films
  3. Etching processes - the films are etched selectively to provide relief following the mask outlines

MEMS Applications

As described at MEMSNet “MEMS promises to revolutionize nearly every product category by bringing together silicon-based microelectronics with micromachining technology, making possible the realization of complete systems-on-a-chip. MEMS is an enabling technology allowing the development of smart products, augmenting the computational ability of microelectronics with the perception and control capabilities of microsensors and microactuators and expanding the space of possible designs and applications.”

MEMS applications are growing fast. They are currently used in:

  • Washing machines – vibration sensors for load imbalance
  • Cars – accelerometers (air bags), roll sensors, ABS
  • Vacuums – dirt sensors
  • Microwave ovens – strain gages for food weight
  • Home theater, cell phones, ear thermometers, stud finders, inkjet printers, game pads for video games, disk drives, robotics, projection displays, and more

SmallTech will help improve and extend your MEMS devices and systems - and help evaluate whether new MEMS application areas make sense for your company.
